As constructed from standardized language test for native speakers, VGaokao involves more language understanding challenges than the datasets constructed from tests for second language learners such as C\(^3\)  [1]} and RACE [2]}.
For example, VGaokao involves more diverse vocabulary and more complex sentence structures. Besides, nearly half of the statements in VGaokao require multiple evidence to verify.
Compared with the fact checking tasks such as FEVER [3]}, where each claim is
tagged with a definite label individually, most statements in VGaokao are not absolutely correct nor absolutely incorrect, which
requires models to carefully compare
one statement with another to choose the most suitable answer according to the given passage.
